[Mediawiki-l] Subdomain Redirects to Top Level

[Crossing Lost]

I am trying to install Mediawiki to a subdomain. I am using the most recent
version 1.6. . .

When I attempt to access mediawiki from my subdomain
http://crossinglost.alt-realities.net/wiki, it reports a 404 Error because
it redirects back to my top level domain
http://www.alt-realities.net/wikiwhere there is no such directory or
file.

I have changed the $IP to '/var/www/crossinglost/wiki' which is the path as
given by my webhost.

Is there another configuration change that needs to be specified?
